NEW QUESTION # 223
A user has been unable to receive emails or browse the internet from a smartphone while traveling. However, text messages and phone calls are working without issue. Which of the following should a support technician check FIRST?
- A. Mobile OS version
- B. Network traffic outages
- C. Data plan coverage
- D. User account status
Answer: C
Explanation:
Explanation
The first thing that a support technician should check to resolve the issue of not being able to receive emails or browse the internet from a smartphone while traveling is the data plan coverage. The data plan coverage determines how much data and where the user can use on the smartphone's cellular network. The data plan coverage may vary depending on the user's location, carrier and subscription. The data plan coverage may not include or support certain areas or countries that the user is traveling to, or may charge extra fees or limit the speed or amount of data that the user can use. The data plan coverage does not affect text messages and phone calls, which use different network services and protocols. User account status is not likely to cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, unless the user account has been suspended or terminated by the carrier or the email provider. Mobile OS version is not likely to cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, unless the mobile OS has a major bug or compatibility problem with the network or the email app. Network traffic outages may cause the issue of not being able to receive emails or browse the internet from a smartphone while traveling, but they are less likely and less common than data plan coverage issues, and they should also affect text messages and phone calls.

This will ensure that any corrupted files or settings are removed and the user's profile is restored to its default state.
NEW QUESTION # 226
A mobile phone user has downloaded a new payment application that allows payments to be made with a mobile device. The user attempts to use the device at a payment terminal but is unable to do so successfully.
The user contacts a help desk technician to report the issue. Which of the following should the technician confirm NEXT as part of the troubleshooting process?
- A. If WiFi is enabled
- B. If NFC is enabled
- C. If airplane mode is enabled
- D. If location services are disabled
- E. If Bluetooth is disabled
Answer: B
Explanation:
NFC stands for Near Field Communication, and it is a wireless technology that allows your phone to act as a contactless payment device, among other things2. Payment applications that allow payments to be made with a mobile device usually rely on NFC to communicate with the payment terminal1. Therefore, if NFC is disabled on the phone, the payment will not work. To enable NFC on an Android phone, you need to follow these steps
3:
* On your Android device, open the Settings app.
* Select Connected devices.
* Tap on Connection preferences.
* You should see the NFC option. Toggle it on.
The other options are not directly related to using a payment application with a mobile device. Airplane mode is a setting that disables all wireless communication on the phone, including NFC4, but it also affects calls, texts, and internet access. Bluetooth is a wireless technology that allows you to connect your phone with other devices such as headphones or speakers, but it is not used for contactless payments. Wi-Fi is a wireless technology that allows you to access the internet or a local network, but it is also not used for contactless payments. Location services are a feature that allows your phone to determine your geographic location using GPS or other methods, but they are not required for contactless payments.
NEW QUESTION # 227
A technician is setting up a new laptop. The company's security policy states that users cannot install virtual machines. Which of the following should the technician implement to prevent users from enabling virtual technology on their laptops?
- A. Restricted user permissions
- B. Secure boot
- C. UEFI password
- D. Account lockout
Answer: B
Explanation:
Explanation
A technician setting up a new laptop must ensure that users cannot install virtual machines as the company's security policy states One way to prevent users from enabling virtual technology is by implementing Secure Boot. Secure Boot is a feature of UEFI firmware that ensures the system only boots using firmware that is trusted by the manufacturer. It verifies the signature of all bootloaders, operating systems, and drivers before running them, preventing any unauthorized modifications to the boot process. This will help prevent users from installing virtual machines on the laptop without authorization.
NEW QUESTION # 228
A management team at a small office wants to block access to inappropriate websites and create a log of these access attempts. Which of the following is a way to meet these requirements?
- A. Content filter
- B. Screened subnet
- C. Port forwarding
- D. Access control list
Answer: A
Explanation:
A content filter is a device or software that blocks or allows access to web pages based on predefined criteria, such as keywords, categories, or ratings. A content filter can also create a log of the blocked or allowed web requests, which can help the management team monitor and audit the web usage of their employees. A content filter is different from the other options because:
* A screened subnet is a network segment that is protected by two firewalls, one facing the internet and one facing the internal network. A screened subnet can isolate servers or hosts that need to be accessed from both sides, such as a web server or a bastion host. A screened subnet does not filter web content based on predefined criteria, but rather on network addresses, ports, and protocols.
* Port forwarding is a technique that allows a router to forward packets from one port to another port, usually on a different device. Port forwarding can enable remote access to services or applications that are hosted on a private network, such as a web server or a game server. Port forwarding does not filter web content based on predefined criteria, but rather on destination ports and addresses.
* An access control list (ACL) is a set of rules that defines which packets are allowed or denied on a network device, such as a router or a firewall. An ACL can filter packets based on source and
* destination addresses, ports, protocols, and other criteria. An ACL can also create a log of the matched or unmatched packets, which can help the management team troubleshoot and secure their network. An ACL does not filter web content based on predefined criteria, but rather on packet headers and fields.

Which of the following wireless security features can be enabled lo allow a user to use login credentials to attach lo available corporate SSIDs?
- A. TACACS+
- B. Preshared key
- C. WPA2/AES
- D. Kerberos
Answer: C
Explanation:
WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

NEW QUESTION # 233
A technician is troubleshooting a mobile device that was dropped. The technician finds that the screen (ails to rotate, even though the settings are correctly applied. Which of the following pieces of hardware should the technician replace to resolve the issue?
- A. Battery
- B. Digitizer
- C. LCD
- D. Accelerometer
Answer: D
Explanation:
The piece of hardware that the technician should replace to resolve the issue of the screen failing to rotate on a mobile device that was dropped is the accelerometer. The accelerometer is a sensor that detects the orientation and movement of the mobile device by measuring the acceleration forces acting on it. The accelerometer allows the screen to rotate automatically according to the position and angle of the device. If the accelerometer is damaged or malfunctioning, the screen may not rotate properly or at all, even if the settings are correctly applied. LCD stands for Liquid Crystal Display and is a type of display that uses liquid crystals and backlight to produce images on the screen. LCD is not related to the screen rotation feature but to the quality and brightness of the display. Battery is a component that provides power to the mobile device by storing and releasing electrical energy. Battery is not related to the screen rotation feature but to the battery life and performance of the device. Digitizer is a component that converts touch inputs into digital signals that can be processed by the mobile device. Digitizer is not related to the screen rotation feature but to the touch sensitivity and accuracy of the display.

NEW QUESTION # 236
A user is attempting to make a purchase at a store using a phone. The user places the phone on the payment pad, but the device does not recognize the phone. The user attempts to restart the phone but still has the same results. Which of the following should the user do to resolve the issue?
- A. Turn off airplane mode while at the register.
- B. Connect to the store's Wi-Fi network.
- C. Enable Bluetooth on the phone.
- D. Verify that NFC is enabled.
Answer: D
Explanation:
The user should verify that NFC is enabled on their phone. NFC is a technology that allows two devices to communicate with each other when they are in close proximity2.
NFC (Near Field Communication) technology allows a phone to wirelessly communicate with a payment terminal or other compatible device. In order to use NFC to make a payment or transfer information, the feature must be enabled on the phone. Therefore, the user should verify that NFC is enabled on their phone before attempting to make a payment with it. The other options, such as turning off airplane mode, connecting to Wi-Fi, or enabling Bluetooth, do not pertain to the NFC feature and are unlikely to resolve the issue. This information is covered in the Comptia A+ Core2 documents/guide under the Mobile Devices section.

NEW QUESTION # 241
A company-owned mobile device is displaying a high number of ads, receiving data-usage limit notifications, and experiencing slow response. After checking the device, a technician notices the device has been jailbroken. Which of the following should the technician do next?
- A. Back up the files and do a system restore.
- B. Restore the defaults and reimage the corporate OS.
- C. Run an antivirus and enable encryption.
- D. Undo the jailbreak and enable an antivirus.
Answer: B
Explanation:
The best course of action for the technician is to restore the defaults and reimage the corporate OS on the device. This will remove the jailbreak and any unauthorized or malicious apps that may have been installed on the device, as well as restore the security features and policies that the company has set for its devices. This will also ensure that the device can receive the latest updates and patches from the manufacturer and the company, and prevent any data leakage or compromise from the device.
Jailbreaking is a process of bypassing the built-in security features of a device to install software other than what the manufacturer has made available for that device1. Jailbreaking allows the device owner to gain full access to the root of the operating system and access all the features1. However, jailbreaking also exposes the device to various risks, such as:
The loss of warranty from the device manufacturers2.
Inability to update software until a jailbroken version becomes available2.
Increased security vulnerabilities32.
Decreased battery life2.
Increased volatility of the device2.
Some of the signs of a jailbroken device are:
A high number of ads, which may indicate the presence of adware or spyware on the device3.
Receiving data-usage limit notifications, which may indicate the device is sending or receiving data in the background without the user's knowledge or consent3.
Experiencing slow response, which may indicate the device is running unauthorized or malicious apps that consume resources or interfere with the normal functioning of the device3.
Finding apps or icons that the user did not install or recognize, such as Cydia, which is a storefront for jailbroken iOS devices1.
The other options are not sufficient or appropriate for dealing with a jailbroken device. Running an antivirus and enabling encryption may not detect or remove all the threats or vulnerabilities that the jailbreak has introduced, and may not restore the device to its original state or functionality. Backing up the files and doing a system restore may not erase the jailbreak or the unauthorized apps, and may also backup the infected or compromised files. Undoing the jailbreak and enabling an antivirus may not be possible or effective, as the jailbreak may prevent the device from updating or installing security software, and may also leave traces of the jailbreak or the unauthorized apps on the device.
